The cpuset_getaffinity() function is checked in sys/cpuset.h to see if
BSD CPU affinity APIs are available. This check requires including
sys/param.h to work properly, otherwise the test program fails with
unrelated errors like:

/usr/include/sys/cpuset.h:155:1: error: unknown type name
'__BEGIN_DECLS'
__BEGIN_DECLS
^
/usr/include/sys/cpuset.h:156:12: error: unknown type name 'cpusetid_t';
did you mean 'cpuset_t'?
int     cpuset(cpusetid_t *);

and so forth.
